I mean, there are three serious top level AI companies, and the only thing they're competing on right now is the quality of their frontier models. Or arguably their ability to raise cash, in an extremely "buzzy" market....
There's definitely more than 3 companies competing for AI talent and you know that very well.
Nvidia, Apple, Google, OpenAI, Anthropic, xAI, Tesla, Microsoft, Mistral and dozens and dozens of well funded AI startups are just among those with more resources.
Apple Tesla and Microsoft arguably really don't count. Microsoft is selling shovels. Tesla is, well, Tesla. Apple is not competing on frontier models, far as i can tell
